Filed: 1993-10-13
Abstract: PURPOSE:To accurately detect an objective work even when a binarized picture is axially symmetrical, etc., by comparing coordinate data calculated form the coordinates of a reference point and characteristic point with preset coordinate data. CONSTITUTION:The picture data obtained by taking the image of an objective work are binarized and the coordinates which become a reference point Po indicating the reference position of the picture are calculated. At the same time, the coordinates of multiple characteristic points M1, M2, and M3 indicating the features having a common relative relation against the reference point Po are calculated on the contour line of the picture. Then the position and attitude of the objective work are detected by comparing the coordinate data calculated from the coordinates of the points Po and M1, M2, and M3 with preset coordinate data. When the binarized picture is linearly symmetrical, the attitude calculation can be performed stably by detecting one or more of the angles theta1, theta2 and theta3 between the segments connecting the coordinates of the characteristic points M1, M2, and M3 with the reference point Po and a horizontal line.

Filed: 1990-09-25
Abstract: PURPOSE: To improve the speed and certainty of retrieved results by receiving signals containing the enciphered version of a P-code pseudo random code sequence and independently generating the replica of the P-code pseudo random code sequence. CONSTITUTION: The received signal of a system is processed and an L2 carrier signal modulated with an enciphered P-code is generated. When the carrier signal is generated, signals transmitted from a plurality of satellites and containing the enciphered version of a P-code pseudo random code sequence are received and the replica of a non-enciphered P-code pseudo random code sequence is independently generated. Then the frequency spectrum containing the peak indicating the temporal relation between the received enciphered P-code sequence and the locally generated replica of the P-code sequence is found, by correlating the former with the latter. The correlated results are band-passed and correlated so that the L2 carrier signal can be reproduced at a desirable S/N and the band-passed signal is squared.

Title: Photodetection sensor for range finding
Inventor: KOTANI TAKAAKI
IPC: G01C3/00
Filed: 1987-10-12
Abstract: PURPOSE:To obtain the sensor which is free from variation of reflected light with the distance of a subject, cross talk, etc. by adjusting the width of photodetectors arrayed in a base length direction in the same direction and setting a photoelectric output at the time of photodetection above a constant level when reflected light arrives from a distance measurement area that each photodetector faces. CONSTITUTION:A subject distance area as an object of distance measurement is divided into distance measurement areas and the photodetectors S1-S6 are arrayed in the direction of the base length L corresponding to them to constitute a photodetection sensor 9. Then the width of the elements S1-S6 in the direction of the base length L is so set that when reflected light beams from subjects at the farthest positions and closest positions in the corresponding areas are incident, the same photoelectric outputs are obtained. Therefore, wherever a subject is in a distance measurement area corresponding to a photodetector on which reflected light is incident, a photoelectric output is obtained which is larger than a constant output larger than the photoelectric outputs from subjects at the farthest position and closest position in the area. This is converted into a binary signal to eliminate the superposition of a false signal under the influence of crosstalk, etc.

Abstract: PROBLEM TO BE SOLVED: To restrain a height low, and make the whole compact by laterally juxtaposing compressed gas storage tanks in a plurality, installing an electric motor on the compressed gas storage tanks, and arranging compression spaces side by side on the electric motor side. SOLUTION: In compressed gas storage tanks 4, the ones formed in a small diameter are laterally arranged by two pieces. An electric motor 1 is arranged at a right angle to the lengthwise direction of the compressed gas storage tanks 4, and is arranged aside to one side on the compressed gas storage tanks 4. On the other side of the compressed gas storage tanks 4, compression spaces 2 and 3 are arranged side by side on the electric motor 1 side. By such constitution, a height can be lowered more than a single large diameter storage tank, and the height can be restrained lower by a quantity of the compression spaces 2 and 3 than a system that compression spaces are arranged on an electric motor.  Since this is the constitution that a useless space is not formed between the tanks 4 and the compression spaces 2 and 3, a compact multistage compressor whose whole height is low can be provided.

Title: Continuous dryer for post-treated film of band metal
Inventor: YAMASHITA RYUICHI
IPC: F26B23/08
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To control the drying temperature of a post-treated film accurately while improving the surface appearance thereof. SOLUTION: A plated band metal 16 applied with a post-treated film is subjected to primary drying in an induction heating furnace 17 and then subjected to secondary drying in a hot air circulation furnace 18. Temperature of the post-treated film is measured by means of first and second thermometers 19, 20, respectively, after primary and secondary drying. A control means 21 controls the induction heating furnace 17 such that the temperature detected by the first thermometer 19 is higher than a specified primary drying temperature and also controls the induction heating furnace 17 and the hot air circulation furnace 18 such that the temperature detected by the second thermometer 20 is equal to a specified secondary drying temperature. Consequently, the drying temperature of the post-treated film is controlled accurately to a specified level.  Since primary drying is performed in the induction heating furnace 17 such that generation of wind pattern due to hot air is prevented perfectly on the surface of the post-treated film, surface appearance thereof is improved.
